Answer:
C
Step-by-step explanation:
The domain of this function is ![[-4,2]](https://tex.z-dn.net/?f=%5B-4%2C2%5D)
, as it is shown in the graph that 
is only within this interval. The range of this function is ![[-4,4]](https://tex.z-dn.net/?f=%5B-4%2C4%5D)
, as the smallest value of 
is -4 and the largest value of is 4, and takes every possible values between them.
10% of 3.99=0.399x4=1.596
1% of 3.99=0.0399x5=0.1995
1.596+0.1995=1.7955
1.8(Rounded)+3.99=5.79

Answer:
The roots of the polynomial are;
3 + 2i
and 3-2i
Step-by-step explanation:
Here, we want to solve the given polynomial using the completing the square method
We start by dividing through by 8
This will give;
x^2 - 6x = -13
To complete the square, we simply divide the coefficient of x by 2 and square it
We have this as -6/2 = -3
square it;; = (-3)^2 = 9
Add it to both sides
x^2 - 6x + 9 = -13 + 9
x^2 - 6x + 9 = -4
(x-3)^2 = -4
Find the square root of both sides
x-3 = ±2i
x = 3 + 2i
or x = 3-2i
